General Description
The HT817D0 is a single chip LOG-PCM voice synthesizer LSI with 16.8-second voice capacity at 6kHz sampling rate. The chip when triggered drives a speaker through an external transistor with a current switch D/A converter output. Negligible current will be consumed in the standby state.
Features
? Operating voltage: 3.6V~5.0V
? Directly drives an external transistor
? Low standby current (1μA typ. for VDD=3V)
? Minimal external components
? 508 words table ROM for key functions
? Programmable silence length and end-pulse width (minimal end-pulse width is 330s at a 6kHz sampling rate)
? 16.8-second voice capacity (based on a 6kHz sampling rate)
? Section options
- Retriggerable
- Non-retriggerable
? FLAG1 options
- End-pulse output

? 12 keys
? Controllable volume
? Key options
- Stop key: KEY12
- Random (only for KEY1)
- Sequential (only for KEY1)
- Repeat (for all KEYs)
- Key debounce time (for all KEYs): 700μs, 22ms, 45ms, 180ms (based on a 6kHz sampling rate of)
